Bugs in the cygwin packaging of coreutils should be reported to cygwin AT cygwin.com. Setting the reply-to: accordingly. What you are seeing is caused by cygwin's auto-.exe extension behavior, and is not a bug in the upstream sources. The problem is that on cygwin, stat(2) on "foo" returns information for "foo.exe" if "foo" did not exist (a cygwin design decision that helps 99% of the time, since Windows does not like executables without extensions but Unix does; but it interferes in this case). The code path for `mkdir -p' uses stat(2) while the code path for regular `mkdir' does not. Now that you've reported it, the cygwin team will probably write a cygwin-specific patch to `mkdir -p' to ignore stat(2) if it appended .exe. - -- Life is short - so eat dessert first!
